A dynamic model of a bulldozer with a semi-rigid suspension

Abstract

This article provides a mathematical description of a complex dynamic system of a bulldozer with a semi-rigid frame’s suspension. The authors have proposed a mathematical model that consists of geometric relations’ equations of the machine elements and differential equations of moving machine frame and operating device under external kinematic and dynamic impacts. The considerable attention in the presented mathematical model is paid to the dependencies between varieties of machine’s structural parameters.
